Abstract

In a servo valve arrangement for hydraulic power assisted steering systems in motor vehicles comprising a rotary spool connected to a steering shaft and a control sleeve receiving the rotary spool so as to permit some relative rotation between the control sleeve and the rotary spool, an axial endpiece is coupled to the rotary sleeve for rotation therewith by an articulated joint structure so as to accommodate any misalignment in the steering system.
